Why does the concentration of tin sulphate solution not change during the electrolysis?

Tin Sulphate stays the same during electrolysis because it is low down in the reactivity series, it can only be extracted by the reduction of carbon, not by electrolysis.

The blue colour of the solution fades during the electrolysis of copper sulfate. Explain why.?
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
What event must take place to separate a compound into separate elements?

Why does the color of copper sulphate change when an iron nail dipped in it?
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Why does adding carbon dioxide to BTB solution cause a color change?
BTB is an acid indicator. by adding carbon dioxide to the solution, it will turn into carbonic acid (a weak acid) turns green in low concentration and yellow in high concentration.
What change will be caused by addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride?
The concentration of fluoride ions will decrease and the concentration of hydrogen fluoride will increase.
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
How does concentration change after every spoon full of salt is added after the solution is saturated?
The concentration of the salt solution does NOT change- it is saturated.

How can the concentration of a solution change?
You add zinc to the solution and add 10% of what is left
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
Is electrolysis of NaCl a chemical change or not?
Electrolysis is a chemical change.
What is the change in conductivity as the concentration of the NaCl solution was increased by the addition of NaCl drops?
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
Does conductivitiy of water change as concentration of sugar change?
No. Sugar solution is not an electrolyte because it has no free charges in the solution to carry the electricity.
What property of solution could you change to get a greater temperature change in endothermic and exothermic reactions?
Concentration.
How do you precipitate soluble complex?
Add salt to the solution. Change the temperature of the solution. Let the solvent evaporate in increase the concentration of the soluble complex. Change the pH of the solution.
Describe the concentration gradient shown in the transparency?
The description of the concentration of a gradient shown in the transparency is a gradual change of solutes that are in a solution. This is a function of distance through the solution in biology.
